First, Find Out Whether It Is Bedbugs
People mistake carpet beetles, spider beetles and even flecks of dirt for bedbugs, particularly on a quick walk round. Before you tell anyone anything or rearrange your viewings, check the bed carefully: mattress seams and piping, the joints of the frame, the headboard fixings and the skirting nearest the bed. Our London guide on whether it is bedbugs or something else helps you tell them apart.
If you still are not sure, book an inspection. It starts from £120 and gives you an answer from someone who looks at bedbugs for a living, which is worth having before you decide anything about the sale.

What to Tell the Agent and the Buyer
Whether and how you have to disclose it is a question for your conveyancer or solicitor, not for us. What we would say is that a confirmed, treated problem is far easier to talk about than a suspected one nobody has looked into. Ask the agent to hold further viewings in the affected room until you know where you stand.
Treating It Around a Sale
Timing matters when you are trying to sell. Heat treatment usually needs one visit: the room is taken to a temperature bedbugs cannot survive, held there, and checked with a thermal camera so no cold corner is missed. It kills eggs as well, so you are not waiting a fortnight to find out if it has worked. The room is usable again once it has cooled.
Chemical treatment costs less but runs over two or three visits about 10 to 14 days apart, because the residue does not reliably reach the eggs. That can fit if completion is some way off, and it leaves a residue that keeps working between visits. Both start from £220; the exact figure depends on the number of rooms and is given on the phone.
Do Not Pack the Problem Into the Van
The worst outcome is a successful sale followed by bedbugs in your new home. Get the treatment finished before you start packing, and in the meantime:
- Do not take the affected bed or mattress to the tip before treatment unless we advise it
- Do not move furniture from the affected room into storage or another room
- Wash and dry bedding and clothes from that room hot before they go into boxes
- Check suitcases and fabric boxes before they are packed, not after they arrive
- Keep the removal company informed if treatment is still running when moving day comes, and ask us how to plan around it

Bedbug Control Leytonstone — Questions
Should I stop viewings altogether?
That is up to you and your agent. Many sellers pause viewings in the affected room until it is confirmed and treated, which also stops visitors carrying anything away.
Could the viewer have brought them in?
It is possible but unlikely from a single short visit. It is more useful to confirm what is there and treat it than to work out where it came from.
Will heat treatment damage the room before photos or viewings?
Heat-sensitive items come out first and we give you the list. The room is back in use once it has cooled.
How quickly can a Leytonstone flat be treated?
Ring us on 0800 955 1018 and we will tell you what we can offer and what the preparation involves, so you can plan around viewings.
